Swoole WebSocket服務端與客戶端 持續更新
簡單WebSocket 服務端實現
server.php
<?php
$server = new Swoole\WebSocket\Server("0.0.0.0", 9906);
//$server->set([
// 'enable_static_handler' => true, // 開啓靜態資源存在優先訪問
// 'document_root' => './', // 靜態資源目錄
//]);
// 監聽WebSocket鏈接打開事件
$server->on('open', 'onOpen');
function onOpen($server,$request){
print_r($request->fd);
}
// 監聽WebSocket消息事件
$server->on('message', function (Swoole\WebSocket\Server $server, $frame) {
echo "receive from {$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}\n";
$server->push($frame->fd, "this is server");
});
$server->on('close', function ($ser, $fd) {
echo "client {$fd} closed\n";
});
$server->start();
簡單WebSocket 客戶端實現
client.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>WebSocket測試</title>
</head>
<body>
<h1>WebSocket測試</h1>
<script>
var wsUrl = "ws://127.0.0.1:9906";
var webSocket = new WebSocket(wsUrl);
// 實例對象的onOpen屬性
webSocket.onopen = function (e) {
webSocket.send("hello!");
console.log("打開鏈接成功！")
};
// 實例化 onMessage
webSocket.onmessage = function (e) {
console.log("接收的內容：",e.data);
};
// 實例化 onClose
webSocket.onclose = function (e) {
console.log("關閉鏈接");
};
// 實例化 onClose
webSocket.onerror = function (e) {
console.log("錯誤：",e.data);
};
</script>
</body>
</html>
訪問
可以直接打開這個html頁面 也可以直接在瀏覽器運行http://127.0.0.1:9906 不過前提是要打開服務端set的內容 並且能生效（因爲筆者的不生效，所以選擇第一種方法）
優化成面向對象

其中 task 異步任務處理 可以返回給用戶信息，並且同時執行任務，從而提高用戶體驗
task不只是可以在WebSocket中使用也可以在HttpServer、TCPServer中使用
其中 異步毫秒定時器 可以按照規則處理數據，從而提高異步進行數據查詢之類的操作
- swoole_timer_after N秒後執行一次
- swoole_timer_tick N秒後執行，循環
- swoole_timer_clear 取消這個定時器
